Answer:

Radiation recall can occur when chemotherapy is given after radiation treatment. When radiation treatment is given, the skin in the radiation treatment field can react with some redness (erythema) that usually resolves within 1-2 weeks after treatment. When chemotherapy is then given after the radiation, sometimes the skin redness can come back again, although usually not as intensely as after the primary radiation treatment. Again, the skin reaction usually resolves fairly quickly. Radiation recall more commonly occurs after certain chemotherapy agents. Radiation recall is usually not a serious problem.
